T-Pain Performs ‘5 O’Clock’ on ‘Leno’ [Video]

T-Pain turned late night to early morning on “The Tonight Show with Jay Leno.” Accompanied by his band and backup singers, the Florida native kicked off the promo for his new album rEVOLVEr by performing his Lily Allen-sampled single “5 O’Clock.” He also showed off his real voice in a skit for comedy website Funny or Die. Wonder what he sounds like without the Auto-Tune? You’ll be surprised.
